The K18 Molecular Repair Hair Oil does more than most hair oils. It nourishes the surface and works on the structure of your hair. Especially if your hair is damaged, you’ll notice a quick difference.

• Reduces frizz for up to 24 hours after use
• Up to 104% more shine visible in your hair
• Protects hair from heat up to 232°C
• Up to 78% fewer split ends over time
• Does not weigh hair down, even fine hair
• Silicone-free with no buildup
• Works on wet and dry hair
• Suitable for all hair types

The oil fits easily into your existing routine and works both as a treatment and a finishing touch. It’s suitable for everyone, from fine and straight to thick and curly hair.

1. Wash your hair with a mild shampoo and towel dry.
2. Shake the bottle and put 1 to 3 drops in your palm.
3. Distribute the oil through your lengths and ends, avoiding the scalp.
4. Wait 4 minutes to let the peptide work.
5. Blow-dry or style your hair as usual.
6. On dry hair, you can add an extra drop as finishing oil for more shine and less frizz.

Want the best results? Combine the oil with the Leave-In Molecular Repair Hair Mask for deeper repair.

Your hair feels stronger and looks smoother and shinier. It starts from within, thanks to K18PEPTIDE™. This small bioactive peptide penetrates deep into the hair fibre and helps repair broken structures. So the oil tackles the root cause of frizz and fragility instead of just masking it.

On the surface, avocado oil and squalane add shine and a smooth touch. Squalane absorbs quickly without leaving a greasy residue. Together, these ingredients give your hair a finish that feels healthy because it truly is. The K18 hair oil is one of the few silicone-free oils that combines styling and repair in one product.

Yes. The oil is specially formulated not to weigh hair down. Start with 1 drop and see how your hair reacts. Users with fine hair confirm it feels light and never greasy if you keep the dose low. That makes the K18 hair oil a great choice for fine or limp hair, which can often be tricky with heavier oils.

Yes, the oil provides heat protection up to 232°C. That’s enough for blow-dryers, curling irons, or straighteners used normally to heavily. Apply the oil before styling for the best protection. For extra security during intense styling, combine it with the Heatbounce Conditioning Heat Protectant for double protection.

Both are repairing styling oils but work differently. K18 oil is completely silicone-free and uses a peptide to repair hair structure from within. Olaplex No.7 leans heavily on silicones for that instant, ultra-smooth finish. If you want silky, almost plastic smoothness, Olaplex No.7 might suit you better. If you want lasting repair and frizz control without silicone build-up, the K18 Molecular Repair Hair Oil is the better choice.

The K18 hair oil does not build a layer, meaning your hair won’t feel heavier over time. This makes it a great option if you want to improve your hair’s condition alongside styling.

Most hair oils do one thing: coat the hair surface for shine and smoothness. The K18 Molecular Repair Hair Oil does that and more. The K18PEPTIDE™ works directly on the hair fibre, not just outside. This product appeals if your hair is damaged, fragile, or porous from colouring, bleaching, or stress.

If you have little damage and just want shine or hydration, a richer, classic oil might do the trick. But if you want to strengthen your hair structurally while styling shiny and frizz-free, the K18 serum oil offers more than a standard hair oil. Also check out the Peptide Prep Detox Shampoo as a starting point for your K18 routine.
